Enabling The Ipv6 Multicast Group Replacement Feature; Displaying And Maintaining Mld Snooping - HP FlexFabric 5700 Series Configuration Manual

Enabling the IPv6 multicast group replacement feature

This feature enables the switch to replace an existing IPv6 multicast group with a newly joined group
when the number of groups exceeds the upper limit. This feature is typically used in the channel switching
application. Without this feature, the switch discards MLD reports for new groups, and the user cannot
change to the new channel.
Configuration guidelines
When you enable the IPv6 multicast group replacement feature, follow these guidelines:
This configuration takes effect only on the multicast groups that the port joins dynamically.
•
You can enable the multicast group replacement feature either for the current port in interface view
•
or globally for all ports in MLD-snooping view. If the configurations are made in both interface view
and MLD-snooping view, the configuration made in interface view takes priority.
Configuration procedures
To enable the IPv6 multicast group replacement feature globally:
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Enable the IPv6 multicast
group replacement feature
globally.
To enable the IPv6 multicast group replacement on a port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Enable the IPv6 multicast
group replacement feature on
the port.
